Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Study of the glass transition in the amorphous interlamellar phase of highly crystallized poly(ethylene terephthalate)

, 2010
Poly(ethylene terephthalate) (PET) is a semi--crystalline polymer that can be crystallized to different degrees heating from the amorphous state. Even when primary crystallization has been completed, secondary crystallization can take place with further ...

Synthesis and characterization of a novel Y-Fe phase via kinetic neutron diffraction [PDF]

, 2001
Kinetic in situ neutron diffraction has been used to study the crystallization of amorphous Y67Fe33. The results show that partial crystallization first occurs close to 300 ◦C where the Y phase is formed.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Modelling of heat transfers and prediction of crystallization during cooling of chicken fat [PDF]

, 2005
Heat transfers that occurred during chicken fat dry fractionation process were characterized. The heat flux model developed led to follow the heat flux associated with crystallization (?r) during the cooling step. A crystallization kinetics was performed

Crystallization of Isotactic Poly(methylmethacrylate) in Monolayers and Thin Films [PDF]

, 1991
Langmuir-Blodgett monolayers of isotactic PMMA exhibit a pressure-induced transition upon compression, that can be described in terms of a two-dimensional crystallization process, analogous to a normal melt crystallization.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
